vars are not very cool in scala... how about something like this?

val (duration, executorRunTime) = if (info.finished) {
      (info.duration, metrics.executorRunTime)
    } else {
      val timeRunning = info.timeRunning(lastUpdateTime.getOrElse(System.currentTimeMillis()))
      (timeRunning, timeRunning)

executorRunTime = metrics.executorRunTime
} else {
info.timeRunning(lastUpdateTime.getOrElse(System.currentTimeMillis()))
duration = info.timeRunning(lastUpdateTime.getOrElse(System.currentTimeMillis()))
executorRunTime = duration
